But Asus is showing off more than just products. The company also is using CES to display a clever concept: Laptops that can share resources with other close-by laptops. Asus calls the concept "Fold/Unfold."

It works like this: Whenever two notebooks are placed close together, they would be able to share resources such as the processor and memory. And, when the two are placed directly together, they can share an interface and even their battery.

Fold/Unfold is only a concept, so there's no guarantee that such a product would ever see the light of day. And there are some security issues that would need to be ironed out, too. But it's a cool idea, and may have some practical real-world uses, such as in schools.
